Question

I am working on an android sms application.I have to send sms to multiple contact.There is method available to send sms to multi contacts so i used for loop.The following is my code.

for (int i = 0; i < to_nums.size();i++) {

                sendSms(to_nums.get(i),  snd_txt.getText().toString() );


        }

public void sendSms(final String phoneNumber, final String message){


    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";
    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
        new Intent(SENT), 0);
    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
            new Intent(DELIVERED),0);

   //--- When the SMS has been sent --

    sendBroadcastReceiver=new BroadcastReceiver() {


        @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub
            switch (getResultCode()) {

                case Activity.RESULT_OK:

                    Toast.makeText(getBaseContext(), "SMS sent",
                        Toast.LENGTH_SHORT).show();

                    break;

                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    Toast.makeText(getBaseContext(), "Generic failure",
                        Toast.LENGTH_SHORT).show();

                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    Toast.makeText(getBaseContext(), "No service",
                        Toast.LENGTH_SHORT).show();



                    break;
                case SmsManager.RESULT_ERROR_NULL_PDU:

                    Toast.makeText(getBaseContext(), "Null PDU",
                        Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_RADIO_OFF:

                    Toast.makeText(getBaseContext(), "Radio off",
                        Toast.LENGTH_SHORT).show();
                    break;



                default:
                    break;
            }
            context.unregisterReceiver(this);

        }
    };



    registerReceiver(sendBroadcastReceiver , new IntentFilter(SENT));






    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);





}

But when I am running my code I am getting an exception ,that says ‘Receiver not registered’. for single receipient it works fone.
.How can I register and unregister in order? Please help me friends.
